Disclosed is a system and a method for setting an internal time corresponding to a standard time at a current location in a mobile station of an asynchronous scheme. The mobile station of the asynchronous scheme uses a Simple Network Time Protocol (SNTP), which is an application of a Network Time Protocol (NTP), allowing the mobile station to easily update internal time information using a synchronized time. The SNTP can provide a time value which can be used to accurately reset an internal time of the mobile station of the asynchronous scheme. By using the SNTP, the mobile station of the asynchronous scheme can obtain exact time information as in a CDMA network and update the mobile station's internal time with the time corresponding to an area in which a standard time is changed.

A watch has a crown for manual time adjustment, a receiver for receiving current time update signals by radio transmission, an internal counter for counting the passage of time according to an internal oscillator, and time display hands. The watch preferably does not have a means for determining the position of its time display hands and therefore relies on user intervention for roughly correlating its time display hands to its internal counter. Preferably, the user begins a manual time correction operation when the second hand is at a predetermined position between 0-60 seconds. When the crown is pushed in, the seconds count value of the internal counter is reset to the predetermined position, and the watch waits for reception of a current time radio signal. When a radio signal is successfully received, the received seconds value is compared to the seconds count in the internal counter. If the time difference is within +30 seconds, the internal time is deemed to be advanced by the difference, and if the time difference is within −30 seconds, the internal time is deemed to be delayed by the difference. The received time data is written into the internal counter, and the time display hands are moved according to the deemed time difference.

Systems and methods that manage effects of discarded SDUs during handover. Aspects of the subject innovation maintain order for arrival of PDCP SDUs when a UE encounters a lost PDCP, which has resulted from a dropped SDU at the source eNB - before assignment of an associated PDCP SN. By initially assigning all SDUs corresponding PDCP SNs, a PDCP SN gap or hole can then be encountered upon dropping of a PDCP SDU. To manage PDCP SN gaps or holes thus generated, an internal time out can be designated to terminate an associated UE's delay for such SN hole(s) via a time out. Other aspects enable the source eNB to send a PDCP Status Message to the UE (via the target eNB) to abort the SN gaps or holes resulting from a dropped PDCP SN.
